Dmitri spent fifteen years navigating the volatile world of commodity trading before realizing that most business owners lacked the financial literacy to protect their ventures during market downturns. His approach combines risk management principles from trading floors with practical budgeting techniques that actually work for small businesses. What sets him apart is his ability to explain complex financial instruments using everyday analogies — he once helped a bakery owner understand derivatives by comparing them to flour futures.

Zaira Pemberton
Educational Program Coordinator
After watching her family's restaurant struggle through the 2020 shutdowns due to poor financial planning, Zaira pivoted from corporate training to financial education. She discovered that most people don't need another investment theory course — they need someone to sit down with them and figure out why their monthly expenses keep exceeding their projections. Her workshops focus on building sustainable financial habits rather than quick fixes, and she's particularly passionate about helping family businesses create succession plans that actually survive generational transitions.
Collective Impact
Our combined experience spans traditional banking, fintech startups, family businesses, and everything in between. We've seen what works, what doesn't, and most importantly, what people actually need to know to make better financial decisions. Rather than drowning you in theory, we focus on practical skills that translate directly to real-world situations.
